Air pollution is an increasing concern to urban residents. In response, residents are beginning to adapt their travel behaviour and to consider local air quality when choosing a home. We study implications of such behaviour for the morphology of cities and population exposure to traffic-induced air pollution. To do so, we propose a spatially explicit and integrated residential location and transport mode choice model for a city with traffic-induced air pollution. Intra-urban spatial patterns of population densities, transport mode choices, and resulting population exposure are analysed for urban settings of varying levels of health concern and air pollution information available to residents. Numerical analysis of the feedback between residential location choice and transport mode choice, and between residents' choices and the subsequent potential impact on their own health suggests that increased availability of information on spatially variable traffic-induced health concerns shifts population towards suburban areas with availability of public transport. Thus, health benefits result from reduced population densities close to urban centres in this context. To mitigate population exposure, our work highlights the need for spatially explicit information on peoples' air pollution concerns and, on this basis, spatially differentiated integrated land use and transport measures.

暴露于交通诱发的空气污染的两阶段居民区位和交通方式选择模型

空气污染已成为城市居民日益关注的问题。作为回应,居民开始选择自己的出行方式,并在选择房屋时考虑当地的空气质量。我们研究了这种行为对城市形态和交通流量引起的空气污染的影响。为此,我们提出了一个空间明确的综合住宅区位和交通方式选择模型,用于城市中交通诱发的空气污染。分析了城市内部人口密度,运输方式的选择以及由此导致的人口暴露的空间格局,以分析不同程度的健康问题和可供居民使用的空气污染信息的城市环境。居民区位选择与交通方式选择之间以及居民之间的反馈的数值分析 选择以及随后对自身健康的潜在影响表明,随着空间变化的交通引发的健康问题,越来越多的信息可得性使人口向郊区地区转移,并获得了公共交通工具。因此,在这种情况下,健康的好处是由于靠近城市中心的人口密度的降低。为了减轻人口暴露,我们的工作强调需要在空间上提供有关人们的空气污染问题的信息,并在此基础上提供空间差异化的综合土地利用和运输措施。在这种情况下,健康益处来自减少靠近城市中心的人口密度。为了减轻人口暴露,我们的工作强调需要在空间上提供有关人们的空气污染问题的信息,并在此基础上提供空间差异化的综合土地利用和运输措施。在这种情况下,健康益处来自减少靠近城市中心的人口密度。为了减轻人口暴露,我们的工作强调需要在空间上提供有关人们的空气污染问题的信息,并在此基础上提供空间差异化的综合土地利用和运输措施。
